100
Moving parts in machinery are coated in oil and grease to reduce this.
What is Friction?
100
This force causes a leaf to fall more slowly than a coin.
What is Drag force?
100
The rate of change in the velocity of an object is called this.
What is Acceleration?
100
This is the product of an object's mass and its velocity.
What is Momentum?
100
This force opposes the movement of an object when it travels through the air or water.
What is Drag force?
200
This is happening to an object when it has negative acceleration.
What is slowing down?
200
The force of gravity acts on an object that has this.
What is Mass?
200
This is the speed of an object in a specific direction.
What is Velocity?
200
A change in the gravitational force acting on an object is its this.
What is Weight?
200
The magnitude of this force is the same as an object's weight.
What is Gravity?
300
In absence of acceleration, a moving object has a constant this.
What is Speed?
300
When the only force acting on an object is gravity, the object is in this.
What is Freefall?
300
An object traveling at a constant speed in a circular path is changing this.
What is Velocity?
300
The force that pull a falling leaf towards earth is called this.
What is Gravity?
300
This upward force acts on an object when it is placed in fluid causing it to float.
What is Buoyant force?
400
The force exerted by a surface that opposes an object's effort to move across it is this.
What is Friction force?
400
The tendency of an object to resist a change in its motion is known as this.
What is Inertia?
400
This is the distance traveled by an object divided by the time taken.
What is Average speed?
400
The force that is applied to an object by a person is called this.
What is Applied force?
400
This is the force transmitted through a string, rope or cable when it is pulled from one end.
What is Tension force?
500
This happens to an object when it has positive acceleration.
What is speeding up?
500
A push or a pull exerted on an object is called this.
What is Force?
500
This is the measure of the amount of an object's matter.
What is Mass?
500
This force is exerted upon an object that is in contact with another object.
What is Normal force?
500
This is what is exerted upon an object when it is in contact with another stable object.
